Flexplate issues

It started with a slight ting ting ting and is starting to get louder.....It made the same noise the last time it cracked, but I was already in Richmond and didn't get over 45 mph....Where on 360 I will do about 55-60 mph......I think I may jus leave it don't want that thought of a tow bill on my head the whole trip!!!!! Let me know what you think
